To all whom it may concern:

Be it known that 1, RAYMOND MOLAUGH- LIN, a citizen of the UnitedStates, residing at Storm Lake, in the county of Buena Vista and Stateof Iowa, have invented a new and useful Th reshing-Machine Separator, ofwhich the following is a specification.

This invention relates to grain separators and more particularly tomechanism whereby the shoe and tailer of a separating machine can becaused to continue to operate in the event of the cylinder of themachine becoming choked and stopping the driving mechanism. This is ofcourse objectionable because it results in the undesirable mixing ofstraw and grain.

Another object is to provide means for operating the shoe and tailer bymomentum in the event of the sudden stoppage of the driving mechanism.

A still further object is to provide simple and efficient means forautomatically coupling and uncoupling the driving mechanism withrelation to the shoe and tailer mechanism.

With these and other objects in view the invention consists in certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

ln the accompanying drawings the preferred form of the invention hasbeen shown.

ln said drawings Figure 1 is a view of a portion of a separator andshowing the presl `ig. 2 is an enlarged plan view of the partsconstituting the present invention. Fig. 3 is a transverse sectionthrough the slidable member of the clutch.

Referring to the figures by characters of reference 1 designates theshaft mounted in suitable bearings `and having an eccentric 3 thereonfor actuating the pitman 4 of the shoe 5. Secured to the shaft at apoint removed from eccentric 3 is a fly-wheel 6, havmounted on the shaft1, and is provided in its outer face with parallel longitudinally eX-tending grooves 14, clearly indicated in Fig. 3. A pulley 15 is looselymounted on the shaft 1, between the sleeve 1.3 and the eccentric 3, oneend of the hub of this pulley preferably bearing against the eccentric3, while extending from the other end of the said hub and from thecorresponding face of the pulley, are guide-plates 16, equal in numberto the grooves 14, and so positioned as to project into these groovesand thus hold the sleeve 13 against rotation upon the shaft 1. A spring17 is coiled around the shaft 1 and bears at its ends against the pulley15 and the sleeve 13 respectively, said spring thus operating to holdthe teeth 12 of the sleeve 13 normally in engagement with the teeth 11on the tubular extension 10.

In the operation of the machine the pulley 15 is designed to be drivenin the direction of the arrow by means of a belt, and, inasmuch as thesleeve 13 is rotated with the pulley and is held in engagement with theteeth 11 by means of the spring 17, it will be apparent of course thatthe fiy-wheel 6 will also be rotated, and the shaft 1 and the eccentric3 thus actuated. Motion will thus be transmitted from the pulley 15 tothe shoe and tailer through eccentric 3 and wrist-pin 7 respectively.Should the cylinder ofthe separator become choked, as is often the casein machines of this character, the mechanism driving the pulley 15 willof course stop, and, ordinarily, this results in the stoppage of theshoe and tailer, with the result that the grain and straw becomecommingled to an undesirable extent. ln the present construction,however, should the pulley 15 stop suddenly, the shaft 1. of the partsconnected thereto will continue to rotate under the momentum imparted tothe fly-wheel 6, and the shoe and tailer will thus continue to work, theindependent rotation of the ilywheel being permitted in view of the factthat the teeth 11 will slip over the non-rotatable teeth 12, forcing thesleeve 13 against the stress of the spring 17. As soon as the pulley 15again begins to operate, the sleeve 13 will rengage the teeth 11 andcontinue to actuate the fly-wheel 6. lt will be seen ltherefore thatduring short stops of the mechanism driving the pulley 15, the shoe andtailer will not cease to operate, and therefore better results areobtained than would otherwise be the case.

l/Vhat is claimed is 1. The combination with a shaft, a fly- Wheelsecured thereto, and driving mechanism actuated by the fly-wheel; of aclutch member movable with the fly-wheel and shaft, a pulley looselymounted on the shaft, guide devices extending laterally therefrom andspaced from the shaft, and a springpressed clutch member slidablymounted on the shaft and engaging said guide devices, said membernormally engaging the first mentioned clutch member.

2. The combination with a shaft, a flywheel secured thereto, a clutchmember upon the fly-wheel and having ratchet teeth, and mechanismactuated by the fly-wheel; of a pulley loosely mounted on the shaft,laterally extending radial guide devices upon the pulley and spaced frombut parallel with the shaft, and a spring-pressed clutch member slidablymounted on the shaft and guide devices, and having ratchet teethnormally engaging the teeth of the first mentioned clutch member.

3. The combination with a shaft, a fly- Wheel secured thereto andrevoluble therewith, mechanism connected to and actuated by thefly-Wheel, and a clutch member upon said fly-wheel and having a circularseries of ratchet teeth, of a pulley loosely mounted on the shaft,laterally extending guide devices disposed radially upon the pulley, andspaced from but parallel with the shaft, a clutch member slidablymounted on the shaft and having longitudinal grooves for the receptionof the guide members, said clutch member having a circular series ofratchet teeth, and a spring interposed between said clutch member andthe pulley for holding said member normally in engagement with theclutch member upon the flywvlieel.

4. In a device of the class described, a shaft, a fly-wheel securedthereto and revoluble therewith, mechanism connected. to and actuated bythe fly-wheel, a clutch member carried by the fly-wheel, a pulleyrevolubly mounted on the shaft, and a springcontrolled clutch memberrevoluble with the pulley and slidable on the shaft into and out ofengagement with the first mentioned clutch member, said clutch membersbeing disposed to automatically disengage during y the sudden stoppageofthe pulley.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
